National Register of Historic Places (NRHP) is the United States
government's official list of districts, sites, buildings,
structures, and objects deemed worthy of preservation. A property
listed in the National Register, or located within a National
Register Historic District, may qualify for tax incentives derived
from the total value of expenses incurred preserving the property.
The passage of the National Historic Preservation Act (NHPA) in
1966 established the National Register and the process for adding
properties to it. Of the more than one million properties on the
National Register, 80,000 are listed individually. The remainder
are contributing resources within historic districts. Each year
approximately 30,000 properties are added to the National Register
as part of districts or by individual Listings.
